Abstract
The embodiments of the present disclosure disclose a method, a device, and a system for UWB communication. The UWB communication method includes: sending a ranging start frame to a plurality of second devices; receiving response frames from the plurality of second devices in a plurality of response time slots; sending a ranging end frame to the plurality of second devices; where each of the second devices maintains at least two sessions with the first device. The embodiments of the present disclosure optimize UWB ranging interactions under a plurality of sessions.
Claims17
An Ultra-Wide Band (UWB) communication method for a first device, the method comprising:
- sending a ranging start frame to a plurality of second devices;
- receiving response frames from the plurality of second devices in a plurality of response time slots, a respective response frame being received in a respective time slot of the plurality of time slots;
- sending a ranging end frame to the plurality of second devices;
- wherein the first device maintains at least two sessions with different second devices concurrently, with a respective session established between the first device and a respective second device of the plurality of second device,
- wherein the respective session indicate that the first device performs ranging interactions with different second devices using different initial parameters.
An Ultra-Wide Band (UWB) communication method for a device, the method comprising:
- receiving a ranging start frame;
- wherein the ranging start frame includes indexes of at least one of response timeslots corresponding to the device;
- transmitting a response frame in the corresponding response time slot;
- and
- receiving a ranging end frame;
- wherein the ranging start frame further includes measurement parameters configured based on at least two sessions, and the indexes are configured in the measurement parameters to support a ranging response executed in one of the at least two sessions.
